Successful Conversion of Corn Stover into Microbial Lipids at High Solids Loading by Rhodosporidium toruloides in Pilot Scale

Caption

Journal of Bioresources and Bioproducts reports a 1 000-L process that converts 20 % solids corn stover into 10.6 g L⁻¹ Rhodosporidium toruloides lipids. After 80-day 6 % NaOH ambient storage, one-hour steam and cloth-squeeze detox, the fed-batch fermentation achieves 93.6 % total reducing-sugar recovery and a palm-oil-like fatty-acid profile without centrifuges, demonstrating scalable, low-energy microbial oil production from agricultural waste.
